I am looking for alternative methods of digital printing.
My project is to print my art at home, but I am not satisfied with the (lack of) artistic quality of commercial laser printers, or inkjet printers. They are not good with colors, usually, don't allow you to print on art paper, the process always uses the same CMYK colors, prints age badly, etc.
I would like the printing process to give additional texture, or specific identity, or to allow a wider range of paper types to the printed works, quite like the Risograph machines do (see here for example). (Some of the Risograph "quirks" include separator marks, smudging, uneven coverage, registration errors, etc.)
But these machines are not really for home workshops: they are meant for large runs of thousands of prints, cost an arm and take up half a room.
And if I went to a local printshop that uses Riso machines and asked them to print 20 different images, they would probably either reject the order or charge me hundreds.
I would like to seek similar results, but to print different images each time, and in a way that doesn't take up too much room in my house.
Maybe such a machine exists, where the user can refill ink themselves (maybe a 1-ink printer that accepts a wide range of inks?), to achieve unique and interesting results? Wikipedia lists a wide range of printing techniques, but it's very difficult to know which ones are best to print art to display or sell. And I am having a hard time thinking that every single one of these technologies has been replaced by the home printer.
What are alternative methods of digital printing that can produce aesthetic or artistic results?
